Kalatope id Al221211: 3 correct images as above.
Is this Persicaria vivipara..??
Location Kalatope, Chamba
Altitude 2100 mts
Habit herb
Habitat wild
Season October
Height 12 inches

I don’t think this is Persicaria vivipara
In Persicaria vivipara the inflorescence is much condensed. Kindly try the link below

… is right. This is not P. vivipara.
For me, it is difficult to say anything without examining the plant more closely. Because, the characteristic pubescence, ochrea, stamens, or nuts can’t be seen here, but somehow it looks like Persicaria longiseta. In other case, P. posumbu.

Pl. check your specimens for these two. Or pl post more close-up shots of the above mentioned characters.

Just sorting through my files.. came across a few better photos of the same plant…

To me it looks like Polygonum sp.

Somehow I could feel that your both the sets are of two different species.
My thoughts are based on mainly with the variation in inflorescence and leaves. Please check this with the original photographs are see whether they are from the same place.
The first set (first mail), I think is Persicaria minor (Huds.) Opiz and the second set (in the later mail) could be Persicaria maculosa Gray . Please check with relevant references.

How thankful I am to you for catching the mistake….!! You are very right… I had made the mistake in gross ignorance and since my folders are jumbled up I did not notice it…
BUT tracing back the time the photograph was taken…
The first photo was not taken at the altitude of 2100 mts but at a LOWER ALTITUDE OF 1300 mts
and the SECOND set was taken at an altitude of 2100 mts….

I appreciate your keen observation and think you are correct.
